My son is 7 months old and has started sleeping from 7:30-8pm to 3-4am on a regular basis (he nurses at 3-4am, then falls back asleep until 6:30-7am). He nurses and drinks about 3oz pumped milk from a bottle before bed. I then pump at 10pm before I go to bed. I'm just wondering - when can I drop this 10pm pump? Or how do I go about dropping it?

Edited to add: I nurse my baby when he's with me, and pump at work and at 10pm to have milk to send to daycare
